Pressure Vessels

Pressure vessels are containers designed to hold gases or liquids at a pressure substantially different from ambient pressure. They are the largest component most tools and machinery need in order to function efficiently.

Rochi is a specialist in fabrication of pressure vessels for compressor technique. Our pressure vessels are manufactured to ASME standards. Critical pressure testing of these products is carried out in-house. Our pressure vessels, used as oil separators, find wide range use in industrial compressors and construction equipment.

Receivers and Dryers

Air receivers are used to store compressed air. The receiver prevents the compressor from running in a continuous run cycle and allows the compressed air to cool. It saves on energy costs and increases the life of compressor. Our receivers are ideal for high-pressure applications.

Air dryers eliminate moisture completely, and increase reliability of production equipment and improve the quality of finished goods. Our weld modules for dryers are widely used in food and beverage, pharmaceutical, pulp and paper, and medical and healthcare services.

Storage Tanks

Industrial storage tanks are containers used for storage of gas, oil, water, or chemicals.

We design and manufacture above ground industrial storage tanks. Our storage tanks are used to store any non-toxic liquid, and find application in storage of fuels, water and oil. These tanks are manufactured as per ASME, ISO 12285-1 and 12285-2 specifications. Our High Temperature/Low Temperature combined tanks for large engines are put to use as cooling water reservoirs for power plants. Critical processes such as welding is done to these standards. Pressure testing of these products is also done in-house.
